Fluid flow occluder and methods of use for medical treatment systems
First Claim
1. An occluder for occluding at least one collapsible tube of a medical infusion device, comprising:
- first and second opposed resilient occluding members defining a space between the occluding members;
a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members; and
a force actuator constructed and positioned within the space to apply a force to bend the first and second occluding members,wherein upon the application of the force by the force actuator to bend the first and second occluding members, the tube contacting member moves between a tube occluding position and an open position; and
wherein the tube contacting member and the at least one collapsible tube are each configured to be positioned fully outside the space between the occluding members during operation of the occluder.

Abstract
An occluder, and methods for occlusion, that employs first and second opposed occluding members associated with each other, a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members, and a force actuator constructed and positioned to apply a force to at least one of the first and second occluding members. The application of the force by the force actuator may cause the tube contacting member to move between a tube occluding position and an open position. A release member may be configured and positioned to enable an operator to manually move the tube contacting member from the tube occluding position to the open position even with no force applied to the at least one of the first and second occluding members by the force actuator. In one embodiment, the force actuator may apply the force sufficient to bend both the first and second occluding members, so that upon the application of the force by the force actuator (such as an air bladder), the first and second occluding members (e.g., spring plates pivotally connected at opposite ends) bend and the tube contacting member may move between the tube occluding position and the open position.
